Authorities have searched his locker at the Horseshoe casino and are awaiting warrants to access his phone and laptop. They also plan to question Tamura’s parents.At Tamura’s apartment, police found a note, medication, a rifle tripod, a revolver box (matching a gun found in his car), and ammunition for both weapons. Police confirmed that Tamura had a history of mental illness, but have not released further details.Tamura had a prior run-in with the law in September 2023, when he was arrested for trespassing after refusing to leave a suburban Las Vegas casino. That charge was later dismissed.Despite his mental health history, Tamura was able to legally purchase a revolver just last month. Nevada’s red-flag law one of 21 in the US, allows authorities or family members to seek a court order to temporarily remove firearms from someone deemed a threat. However, no such request was made in Tamura’s case. A new Nevada law, effective this month, also allows police to immediately seize firearms from people placed under mental health crisis holds.
